lIn lcirculatingheaters wherein the v@heater,-is y vused as al'heatingmedium,v theoil` is fed toafdrum plied to conventional oil drumswithout the use of tools, the device being collapsible or foldable sothat it may be passed through the front door of the heater.

Another object of this invention is to provide a device of this kindembodying a circular plate formed in two halves hinged together withsupporting feet on the outer portions of the plate for engagement withthe top of the oil drum, the plate being supported by the feet apredetermined distance above the drum and having a diametersubstantially the same as that of the drum, so that the plate will beheated to a relatively high degree and will form a radiant heatingmedium in addition to deilecting the heat and names laterally toward thewalls of the heater. y

A further object of this invention is to provide an attachment of thiskind which is of simple and rugged construction and can be produced atsmall cost sor that it will not add unduly to the cost of the heater andcan be purchased separately for mounting on a heater at present in use.Y

With the above and other objects in view, our invention consists in thearrangement, combination and details of construction disclosed in thevdrawings and specification, and then more particularly pointed out inthe appended claims.

In Ythe drawing,

Figure 1 is a plan view, partly broken away yof an attachment for acirculating heater constructed according to an embodiment of thisinvention, showing the device mounted on top of the oil drum,

Figure 2 is a sectional View taken on the line 2-2 of Figure 1, with thedrum removed,

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure1.

Referring to the drawing, the numeral I designates generally a circularplate which is formed oi.' a pair of semi-circular half members II andI2. The members II and I2- are provided on,

' their :router :marginal Vedges .with depending xanges I 4 1 and .r1.5respectively ilfor `:reinforcing l.the @plate :members .L I I i and fI2. s'I'heratwo plate members. I I'fand.

I9:and' 2li,l and 2i andi-:22, respectively, 'which -are 'carried byvithefzsplate members II and I2. f f

In order to provide a means whereby the plate members II and I2 when inhorizontal operative position may be supported above the top of an oildrum generally designated as 23 and of conventional construction, wehave provided pairs of feet 24 and 25 which are xed to or formedintegral with the plate members Il and I2 and project both outwardly anddownwardly therefrom. The feet 24 and 25 are adapted to engage anannular rim or flange 26 which is carried by the top of the drum23,being removably mounted on the rim 26 and held against lateralmovement by extending downwardly a slight distance from the upper end ofthe drum 23. as shown in Figure 3.

The plate member Il is formed with an opening 21 inwardly from themarginal edge thereof and the plate member I2 is formed with a similaropening 28. rIhe openings 21 and 28 'are provided so that a. limitedamountk of heat, names or products of combustion may pass through theplates II and I2.

In the use of this device, the attachment comprising the hinged platemembers II and I2 may be mounted in a, heater of present construction byextending the plate members II and I2 through the doorof the' heaterwhich opens into the repot. In most heaters of this type the door isround and of fairly small size and in order to position the attachmentwithin the heater the two plate members II and I2 are rocked toward eachother to collapse the device and allow for its being passed through thesmall door opening. After the device is within the heater, the two platemembersk II and l2 are swung outwardly to substantially horizontalalignment with each other, and the feet 24 and 25, are kthen engaged ywith the rim 26 of the drum 23.

The fuel is lighted in the conventional manner in the lower portion ofthe drum 23 and the ames or products of combustion rising in the drum 23will pass outwardly inthe space 29 which is formed between the platemembers II and I2 and the upper edge of the drum 23. A portion of theflames or products of combustion may also pass through the openings 21and 28. With an attachment as hereinbefore described, the flamesgenerated in the oil drum 23 and rising from the open upper end thereofWill be deflected laterally toward the walls of the rebox so as to morethoroughly heat these walls than would be the case when the flames risevertically upward from the top of thedrum 23.

We do not meanl to confine ourselves to the exact details ofconstruction herein disclosed but claim all variations falling withinthe purview of the appended claims.

What is claimed is: 1. A deilector attachment for use in the upwardlyopening oil drum of a circulating heater i of the liquid fuel burnertype comprising a circular plate formed of semi-circular members, saidmembers having transverse edges adapted for abutted engagement to forma, close fitting assembly, dependent flanges carried by theouterperiphery of said members, and feet members carriedby said platehaving dependent portions that extend below and outwardly of saidflanges for engagement with the drum to space said plate above andextending outwardly of the drum opening, said flanges extending aboutthe semicircular edge of each member only, rwhereby when they areassembled in the manner recited a continuous circular flange about theentire assembly is thus formed.

4 2. An attachment as defined by claim 1 including apertures formed inthe plate withsaid apertures equally spaced at each side of the abuttededges of the members to provide release means for hot gases pocketedwithin the flanges of said plate.
